Senior lab technician admits mega bridge bogus concrete tests

A senior lab technician has admitted faking tests on concrete that was used in the construction of Hong Kong-Macao-Zhuhai bridge.

Mak Pui-shing, a supervisor at a government-contracted lab admitted to the District Court that he signed papers defrauding the authorities even though he knew the concrete tests were not done properly, RTHK reports.

The court heard that the defendant had told investigators that the quality of the concrete bricks was not affected.

In mitigation, his lawyer said Mak is very sorry and remorseful.

The lawyer said Mak now understood that even though there was a shortage of manpower at the time, that was no reason for him to conduct "a very stupid act" and he's now willing to fully take his criminal responsibility.

Last week, another technician, Ng Kai-yiu pleaded guilty to conspiracy to defraud, after manipulating test reports. He has been remanded to custody, pending his sentencing.

In December Wong Kwok-yiu – who was employed by a government contractor and had input a measurement incorrectly – was jailed for eight months after admitting he had falsified tests.

The ICAC investigation into test manipulations has linked 21 people to the case. Their arrests last year had sparked fears about the safety of the multi-billion dollar project. But the government says subsequent checks have found no problems.
